SPECIFICATION forming part of Letters Patent No. 776,976, dated D m r 6,1904.

Application filed December 5, 1903. Serial No. 183,905- (No model.)

To atZZ whom, it may concern.-

Be it known that I, CHAnLus E. W'nirrLn, a citizen of the United States,and a resident of North Charleston, in the county of Sullivan and Stateof New Hampshire, have invented a new and Improved Chair, of which thefollowing is a full, clear, and exact description.

This invention relates to improvements in camp chairs or stools, anobject being to provide a chair so constructed that the seat may bereadily raised or lowered as occasion may require and the back of whichmay be arranged straight or at any desired angle or inclination by theperson while sitting in the chair.

I will describe a chair embodying my invention and then point out thenovel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a perspective view of a chair embodying my invention. Fig. 2is a sectional elevation thereof. Fig. 3 is a fragmentary View, partlyin section, showing the manner of attaching the rear end of the seatmaterial; and Fig. 4c is a detail view showing a means for locking theseat-roller.

The chair comprises rear legs 1 and front legs 2,the said front and rearlegs being crossed and pivotally connected by a cross-bar 3. The back,comprising a frame 4:, is removably attached to the seat portion of thechair. As here shown, the lower cross-bar 5 of the back rests upon theupper portions of the legs 2, and on the downwardly-extended portions ofthe side members of the frame are pivotally connected arms 6, providedwith notches 7, designed to receive the extended ends of the cross-bar3, so as to hold the back at any desired inclination or straight up anddown. The back material 8 consists of canvas or the like and is attachedat its lower end to the cross-bar 5 and at its upper. end to a crossbar8.

The seat 9 consists of canvas or similar fabric and is attached at itsfront end to a crossbar 10, connected to the upper ends of the legs 1,and at its rear end it is connected to a roller 11, removably engaged inrecesses formed in the upper portions of the legs 2. As here shown,these recesses have circular portions 12 and offsets 13, having parallelwalls designed to engage with the angular ends 14C of the roller, soasto prevent the roller from turning while these portions lt are in therecesses 13. In order to strengthen the upper ends of the said legs, 1provide them with metal plates 15, having openingscoincident with therecesses 12 and 13. Extended through the upper ends of the legs 2 is acrossbar 16, over which the said material passes, and this cross-bar isrcmovably engaged in hooks 17, formed on the back of the side members 4of the back-frame. By means of the hooks 17 engaging with the cross-barthe whole chair may be lifted and carried about by taking hold of theback. Cbviously by unwinding the seat material 9 on the roller 11 theseat will be lowered, and by winding the said material on the roller itmay be elevated, as desired. In order to rotate the roller, it is movedinto the circular portions 12 of the recesses, and after the winding orrolling it is permitted to pass its angular ends into the portions 13 ofthe recesses, and thus the roller will be rigidly locked.

When it is not desired to use the back, it may be readily removed byreleasing the roller from the legs and lifting the bar 16 from the openhooks 17, and thus a stool is formed.

The seat material 9 will be of suiiicient length to permit the swingingof the legs sufiicientl y down so that said seat material may form apillow or head-rest.

Havingthus described my invention, 1 claim as new and desire to secureby Letters Patent 1. A chair comprising crossed pivotallyconnectedlegs,a detachable back-frame, hooks on said back-frame, a cross-barconnecting the upper ends of the front legs and adapted to engage insaid hooks whereby the chair may be lifted by the back, a rollersupported by the upper ends of the said front legs, means for holdingthe roller from rotary motion, and a seat material connected to theupper ends of the rear legs and to said roller.

2. A chair comprising crossed pivotallyconnected legs, a detachableback-frame, hooks on said back-frame, a cross-bar connecting the upperends of the front legs and adapted to engage in said hooks whereby thechair may be lifted about by the back, a roller removably supported bythe upper ends of the said front legs, means for holding the roller fromrotary motion, a cross-bar connecting the upper ends of the rear legs,and a fabric seat material connected to said cross-bar and I0 to saidroller.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
